Ben Cousins 'threatened to kill ex-partner and had drugs concealed in his body’

Former AFL star Ben Cousins allegedly threatened to kill his former partner and bury her alive before he was arrested outside of her Western Australian home.

Cousins, 40, was also rushed to hospital after his arrest because police found that he had allegedly concealed an illicit drug on his person and had to get it medically removed.

Officers who attended the Canning Vale home of Maylea Tinecheff, who rang Triple zero after Cousin's alleged threats around 6.12pm, claim the former footballer had hidden 13g of methylamphetamine in his body.

He is now accused of 16 crimes, including the possession of a drug with intent to sell, threatening to injure or harm another person, and two counts of breaching a family violence or restraining order.

During an appearance at Armadale Magistrates Court today, it was revealed Cousins had allegedly confronted Ms Tinecheff and held a screwdriver to her face.

"I'm going to kill you, going to take your life and freedom and things you love the most," he is understood to have said to his ex-partner.

After being fronted by police, Cousins also allegedly concealed the drug inside a plastic bag in his body, and when police asked him to remove it, allegedly attempted to further conceal it.
